advance, and for finding the advance corresponding to an offset,
useful for positioning and drawing a cursor.

Switch a few places to using android::canvas
instead of SkCanvas as well which eliminated
some JNI

Stop assuming that a Java Bitmap has a SkBitmap* that
has some externally managed lifecycle, and instead switch
a bunch of users to accessing the bitmap by providing
their own SkBitmap* on which to set the (ref counted!)
SkPixelRef* instead

This patch adds a method to determine whether a typeface has a glyph
to support a particular Unicode character or sequence.
The implementation is based on shaping the text and checking for the
presence of .notdef glyphs, and counting the number of glyphs in the
ligature case. In the case of variation selector control characters, it
currently just returns false because there is no variation selector
support yet (Mongolian Free Variation Selectors work because they're
shaped with GSUB instead).

Originally, stroke width is independent of group scaling.
But that is a bug and causing animation trouble.

The cursor position calculation of not well known CharSequence implementation
has problem. getTextRunCursor() returns the relative path of passed string
buffer, so need to fix the origin by adding the copied buffer origin.

Ensures changing configurations mask is propagated to the host drawable
so that it can be properly cleared from cache on configuration changes.
Also fixes constant state handling of the mask in the Inset and Rotate
drawables.
Hides new ColorStateList methods related to theming, since they should
only be used during preloading or internally by framework drawables.
Fixes bug where the cached versions of themeable ColorStateLists were
modified by calling applyTheme() on the host drawable.
Also cleans up some docs and naming in GradientDrawable.

Always update layer bounds if the contained drawable changed in any
way. Also adds null annotations in LayerDrawable and throws a more
useful exception when the layers argument is null.
